3 Copyright Pearson Prentice Hall Earth as an Island All organisms on Earth share a limited resource base and depend on it for their long-term survival. To protect these resources, we need to understand how humans interact with the biosphere.

4 Hunters and Gatherers Adapted to Their Environments They hunted animals and gathered plants for food If there was no food they would move They depended on natural environment for shelter They lived in caves and rock shelters – Made shelters out of: branches, plant fibers, animal skins

7 Fire 500,000 years ago-Ancient people learned to make and control fire – Provided heat and light – Protection from animals – Cooking – Temper (harden) tools

8 Development of Technology All of the ways people apply knowledge, tools, and inventions to meet their needs. 2 million years ago- stone tools for cutting, storage bags, and stone hand axes were created. Hunting bows made of wood Flint spearheads and metal tools Used for: – hunting – Building shelter The results equaled control over environments and a better way of life.

10 The Green Revolution The green revolution was an effort in the mid-twentieth century to increase global food production through modern plant breeding and agricultural techniques. Over the last 50 years, the green revolution has helped world food production double.
